Question
Earthquakes are essentially sound waves—called seismic waves—traveling through the earth. Because the earth is solid, it can support both longitudinal and transverse seismic waves. The speed of longitudinal waves, called P waves, is 8000 m/s Transverse waves, called S waves, travel at a slower 4500 m/s. A seismograph records the two waves from a distant earthquake. The S wave arrives 2.0 min after the PP wave.How far away is the Earthquake. Assume that the waves travel in straight lines, although actual seismic waves follow more complex routes.
Answer:
The distance is
Explanation:
From the question we are told that
The speed of longitudinal seismic wave is
The speed of Transverse seismic wave is
The time difference between the arrival of longitudinal seismic with respect to Transverse waves is
Generally the time difference between the arrival of longitudinal seismic with respect to Transverse waves is mathematically represented as

Answer:
We can apply Boyle's law here, which state that for a fixed temperature and amount of gas, the volume of a gas is inversely proportional to the pressure. Thus,
PV = constant
780 x 100 = 880 x V
V = 88.6 ml
Would presume you are asked to find the volume, since there is no second volume.
By General Gas Law:
P₁V₁/T₁ = P₂V₂/T₂
1.6 * 168 /255 = 1.3*V₂/285
V₂ = 1.6 * 168 * 285 / (1.3*255)
V₂ = 231.095
Final volume ≈ 231 cm³
